What P2E07 means
P2E07 is the high-side circuit fault of gear lever position sensor B: its signal reads above anything the sensor may legitimately produce. An interrupted signal line on an input with pull-up, a short to battery or reference voltage, or a broken sensor ground are the classic causes. No maker publishes P2E07. On the Cadillac XT4 electronic shifter GM monitors sensor 2 axis by axis and sets P089D or P08A2 above 95 % duty cycle, 3 out of 4 samples on a 25 ms loop, Type B. Sensor A carries the selector meanwhile, which is the purpose of the redundancy described in GM's patent. P2E06 is the low fault of the same sensor and P2E03 the high fault of sensor A; both A and B high at once suggests a shared ground or connector.
P2E07 at a glance
- Check engine lightYes, usually on
- Emissions testNot an emissions code
- Limp modePossible
- Repair difficultyMedium
- Typical labor0.5 to 3 hours
- Clears after repairWhen cleared with a scanner
Symptoms of P2E07
- Warning lamp and shift-system message
- Normal shifting via sensor A
- With P2E03 present as well, range selection may be blocked
Common causes of P2E07
- Most likelySignal line of sensor B open
- PossibleGround of sensor B broken
- Less likelySignal line shorted to battery or reference voltage
Check the most likely causes first. Replacing parts by guesswork is the most expensive way to clear a code.

What each part of P2E07 means
| P | Powertrain system: engine, fuel system, ignition, emissions and transmission. |
| 2 | Generic code (second SAE range): it means the same on every make. |
| 07 | The exact fault in that area. |
What to do next
- Note P2E07 and any other codes stored with it: several codes together often point to one cause.
- Check for loose connectors and damaged wiring around the parts the code names.
- Check open recalls for your car: some faults are fixed for free by the dealer. Enter your VIN.
- Clear the code only after the repair. If it comes back, the fault is still there.
Buying a used car? Scan it for stored codes before you pay. A recently cleared memory can hide a problem.
Questions about P2E07
What does P2E07 mean?
P2E07 means "Gear Lever Position Sensor B Circuit High". P2E07 is the high-side circuit fault of gear lever position sensor B: its signal reads above anything the sensor may legitimately produce. It is a generic code, so it means the same on every make.
Is it safe to drive with P2E07?
Drive gently and only to a workshop. With P2E07 the car can go into limp mode (reduced power) to protect itself.
Will P2E07 fail an emissions test?
P2E07 is not an emissions code, so on its own it usually does not fail an emissions test. Other stored codes or a lit check engine light still can.
How hard is P2E07 to fix?
Difficulty: medium. A typical repair takes 0.5 to 3 hours of work. This is a job for a workshop.
Will P2E07 clear itself after the repair?
Clear the code with a scanner after the repair. If the fault is fixed, it does not come back.
